There's also a rhythmic variant of Shepard tones called Risset
accelerando. This page has supercollider code to generate one from a
recorded beat, as well as an MP3 recording:


When I read the OP I thought of this since it's a kind of self-similar
structure so might be thought of as fractal...


(Actually the code would probably do shepard tones as well as risset
rhythms, if you just feed it a constant tone as audio input)
